Psychomotor Objectives

    10. Anatomy and Physiology of the Airway

    11. Basic Airway Management Airway is always assessed first. Advanced techniques are used after basic management. The first step is opening the patient’s airway. Once the airway has been cleared, determine the need for an airway adjunct.

    12. Gastric Tubes Provide channel into patient’s stomach Nasogastric tubes: Inserted through the nose Orogastric tubes: Inserted through the mouth Nasogastric tubes: Contraindicated in a patient with major facial, head, or spinal trauma

    13. Equipment Proper-sized tubes Catheter-tipped 60-mL syringe Water-soluble lubricant Emesis container Tape Stethoscope Suctioning unit and catheters

    14. Gastric Tube Insertion Measure the tube. Lubricate the distal end of the tube. Place the patient in proper position. Pass the tube until you reach the tape marker. Confirm proper tube placement. Aspirate air and stomach contents with the syringe. Secure the tube in place with tape.

    15. Sellick Maneuver Visualize the cricoid cartilage. Palpate to confirm its location. Apply firm pressure on the cricoid ring. Maintain pressure until intubated.

    16. Endotracheal Intubation Insertion of a tube into the trachea in order to maintain the airway Orotracheal intubation: Through the mouth Nasotracheal intubation: Through the nose EMT-Bs only intubate patients who are: Unresponsive with no gag reflex In cardiac arrest

    17. Equipment (1 of 2) BSI equipment Proper-equipment endotracheal tube (ET tube) Laryngoscope handle and blade (visualized technique) Stylet or light stylet 10-mL syringe Oxygen, with BVM device

    18. Equipment (2 of 2) A suctioning unit with rigid and soft-tip catheters Magill forceps Towels for raising the patient’s head and/or shoulders A stethoscope Water-soluble lubricant for tubes and scopes A commercial securing device or tape

    19. Laryngoscope Sweeps the tongue out of the way and aligns the airway Has a light powered by batteries in handle Has blades that connect to handle Blades are curved or straight. They range in size from 0 to 4.

    20. Curved Blade

    21. Straight Blade

    22. Endotracheal Tubes Tubes come in many sizes, from adult to infant. Normal tube-to-teeth mark is usually around 22 cm. Diameter for normal adult male ranges from 7.5 to 8.5 mm. Diameter for normal adult female ranges from 6.5 to 8.0 mm. Use tape or chart for pediatric sizes.

    23. Stylet Plastic-coated wire may be inserted in the ET tube to add rigidity and shape to the tube. Bend the tip of the stylet to form a gentle curve in adults. Bend the tip of the stylet to form a hockey stick shape for an infant and child. Confirm that the stylet is not sticking out past the end of the ET tube.

    24. Syringe Use the 10-mL syringe to test for air leaks in the ET tube before intubation. After the ET tube has been properly inserted, inflate the cuff with 5 to 10 mL of air. Remove the syringe from the pilot balloon to prevent air from leaking.

    25. Other Equipment Oxygen A suctioning unit A BVM device Magill forceps Towels for raising the patient’s head or shoulders Secondary confirmation device C-collar backboard

    26. The Intubation Procedure First EMT-B applies AED. Second and third EMT-B perform CPR. Fourth EMT-B prepares and intubates patient.

    27. Visualized (Oral) Intubation (1 of 2) Open airway. Insert an oropharyngeal airway. Preoxygenate the patient. Assemble equipment. Position the head and neck.

    28. Visualized (Oral) Intubation (2 of 2) Grasp laryngoscope with left hand. Visualize vocal cords. Insert ET tube. Inflate balloon. Confirm placement. Secure tube.

    29. Blind (Nasal) Intubation (1 of 2) Many of the steps are the same as those for oral intubations. Preoxygenate the patient. Check for gag reflex. Insert tube through nostril. Pass tube through vocal cords as patient is inhaling.

    30. Blind (Nasal) Intubation (2 of 2) Release the jaw and hold tube against nostril. Inflate cuff. Attach the BVM device. Confirm placement. Secure the tube.

    31. Intubation Complications Intubating the right main stem bronchus Intubating the esophagus Aggravating spinal injuries Taking too long to ventilate Patient vomiting Soft-tissue trauma Mechanical failure Patient intolerant of the ET tube Decrease in heart rate

    32. Multilumen Airways Inserted without direct visualization Provide ventilation when placed in either trachea or esophagus

    33. Esophageal Tracheal Combitube (ETC)

    34. Combitube Contraindications Conscious or semiconscious patients with gag reflex Children younger than 16 years Adults shorter than 5' Patients who have ingested a caustic substance Patients with esophageal disease

    35. Inserting the ETC (1 of 2) Assemble and check the proper equipment. Apply water-soluble lubricant to the ETC. Position the patient. Preoxygenate the patient. Lift the lower jaw and tongue.

    36. Inserting the ETC (2 of 2) Guide the ETC along the base of the tongue. Inflate the blue and then the white pilot balloon. Ventilate the patient. Confirm placement. Monitor the patient.

    37. Removing the ETC Be prepared to suction patient. Deflate both balloon cuffs. Gently remove the tube.

    38. Pharyngeotracheal Lumen Airway (PtL)

    39. PtL Contraindications Conscious or semiconscious patients with gag reflex Children younger than 14 years Adults shorter than 5' Patients who have ingested a caustic substance Patients with esophageal disease

    40. Inserting the PtL (1 of 2) Assemble and check equipment. Lubricate tube with water-soluble lubricant. Position the patient. Preoxygenate the patient. Lift the lower jaw and tongue. Hold the PtL so that it curves in the same direction as the pharynx.

    41. Inserting the PtL (2 of 2) Inflate balloon cuffs. Ventilate patient through the short, green tube. Evaluate placement. Verify that the patient is receiving adequate ventilations. Monitor the patient.

    42. Removing the PtL Be prepared to suction the patient. Deflate balloon cuffs. Gently remove the tube.

    43. Laryngeal Mask Airway (LMA)

    44. LMA Contraindications Asthma COPD Leaking mask Active vomiting Esophageal diseases

    45. Inserting the LMA (1 of 2) Assemble and check equipment. Open the airway. Preoxygenate the patient. Select proper size. Hold LMA down. Remove oropharyngeal device and begin insertion.

    46. Inserting the LMA (2 of 2) Insert until you feel resistance. Stabilize the tube. Inflate mask. Confirm placement. Insert bite block and secure the LMA.
